Once you have completed your  SketchUp model you can export it in various formats. We explore various methods and show you how in our SketchUp courses. 
For instance you can export 3d models to other programs in either 2d or 3d formats. For 2d images, JPEG is popular for images uploaded to websites and for sending drafts to clients. Basically anyone with a computer can open a JPEG. PNGs are also a popular format for websites and digital devices. TIFFs are used more for commercial printing, either magazines or billboard posters. These files are much bigger than the the compressed JPEG, but are of better print quality.
The free Make version of SketchUp also allows you to export to the COLLADA (.dae) format for use in a variety of 3d programs. You can also upload models to Google Earth via the Place Model command, in the KMX format, or to the 3D Warehouse.
SketchUp Pro has even more export options. In 2d you can export as a PDF, again useful for sending to a client or a printer, since anyone with a computer can open a PDF via the free Adobe Reader program (download from www.adobe.com). Pro also allows you to export as an EPS which, whilst an older format, is still favoured by some printing professionals. You can also export as a DWG (Autocad’s native format), or as a DXF, the file sharing format for various CAD-based programs. 3ds is another 3d format available.
And for sending to a 3d printer, the OBJ format is the one most easily recognized. Animations of fly-throughs or walk-throughs are exported as AVIs for Windows users and MOV files for Mac users.
